Strategy for improving the prognosis of patients with intrahepatic cholangiocarcinoma by surgical treatment : Considerations based on experience and a literature review

Abstract

The prognosis of patients with intrahepatic cholangiocarcinoma (ICC) is still poor, and the 5-year survival rate in patients undergoing radical surgery (R0) is less than one-third. Since the prognosis depends mainly on tumor factors, so early diagnosis is necessary. To extend the survival time of these patients with a poor prognosis, cases of long-term survival were examined based on the results of our experiences and the literature. It was found that the hepatitis virus was highly involved in the carcinogenesis of ICC, and patients who were infected with hepatitis virus had rather good survival. J. Med.
